Hi Helen,
Customer is looking for a low cost solution.
They will consider TPS61170 if its cost is lower than MC33063A.
From TI website... MC33063A is USD0.20/pc and TPS61170 is USD1.00/pc.
Please advise.
Thanks.
the operation frequency of MC33063 is lower than 100k. You would have to use large inductor, at least 150uH-300uH, the size of the 1A inductor wouldbe very big, and the indcutor is expensive. At the same time, you would have to use more output filter ceramic capacitors because of the lower operation frequency.
While the opreation frequency of the TPS61170 is 1.2MHz, an 15uH inductor is enough for the operation. the total solution size is smaller than that of the MC33063. And the actual cost of the TPS61170 is only about 0.2$.
could you please share your application with us, like in what kind of equipment? Volume? My email address is helen-chen@ti.com
